I would like to buy a ssd for my laptop, to do some video editing projects on it, in my country I found this 2 ssd, looking around I've found great reviews about each so I really don't know which one to buy, I have a crucial ssd and it's great but sadly the person who sold it to me doesn't have crucial right now, which one do you think will be better for my purpose.

I really like the Samsung 840 Pro 128GB choice for a OS/programs drive for a desktop PC. It sounds REALLY small for a laptop unless you will have a 2nd drive on the laptop as well.

For a single drive laptop the 500GB Samsung 840 (non-pro) is pretty nice and cost effective vs. the 840 pro 512GB model. For the larger SSD sizes the write speed of Samsung's 840 series is not nearly so crippled as their smaller (120GB) drive is.

If 500GB or larger SSD choices are clearly out of your price range, then the Seagate 750GB Momentus XT 7200 rpm laptop drive would be a good choice.
